i. A process of treating slinies comprising filling a vat therewith, said vat having a filtering surface therein, creating and maintaining a ma "cum vacuum until a cake of the shines is formed upon said surface, diminishing said vacuum, discharging the nonadhcring slirnes'from the vat, filling the vat with a reagent allowing the reagent to permeate the cake removing said reagent, and dischargmg said cake by water and air pressure .hehind said surface.

A process of treating shmcs comprising teri v surface therein, creating a vacuum behind surface until a cake of the sliincs is depos .ed thereon, reducing the vacuum, rcrnoving the non-adlwrhig shines from said 2 vat, filling said vat with a rc-agent, incrcas- 3 ing the vacuum until said rc-agcnt is drawn i through. said cake, decreasing said vacuum, removing said reagent, filling thc vat with a solvent, increasing said vacuum until the l valui are witiulrawn from the cake and discharging the calrc by fluid pressure behind said filtering-surface.

7. A process of treating slimcs comprising filling a vat therewith, said vat having a fill filling a vat therewith, said vat having a illtherein, creating a vacuum behind said filtertering surface therein, creatingavacuum'ba hind said surface until a cake of the shmes is deposited thereon, reducing the vacuum, rc-

moving the non-adhering slimes from said vat, filling said vat with a reagent, increasing the vacuum until said re-agent is drawn through said cake, decreasing said vacuum, removing said re-agent filling the vat with a solvent, increasing said vacuum until the values are withdrawn from the cake and discharging the cake by Water and air pressure behind said filtering surface.

8. A process of treating slimes consisting of adding lime thereto, filling a vat with said slimes, said vat having a filtering surface therein, creating a vacuum behind said filtering surface whereby a cake of slimes is formedupon said surface, discharging said cake and treating said surface with hydrochloric acid to'remove calcareous deposits from said filtering surface.

9. A process of treating slilnes consisting in adding lime thereto, filling a vat with said slimcs, said vat having a filtering surface therein, creating a vacuum behind said filtering surface whereby a cake of slimes is formed upon said surface, discharging said cake and drawing hydro-chloric acid through said filtering surface.

10. A process of treating slimcs consisting in. adding lime thereto, filling a vat with said.

slimcs, said vat having a filtering surface ing surface, whereby. a cake of slimcs is formed upon said surface, discharging said cake, drawing hydro-chloric acid through said filtering surface and forcing water out vvurdly through said surface.
